The water flow is hindered when passing through the rectangular plate, and the flow rate is slowed down, thereby increasing the contact time and heat exchange area between the water flow and the power components, making the heat exchange more thorough and further improving the heat dissipation effect. Liquid nitrogen is filled in the cooling pipe. The water flows out of the water-passing plate and returns to the water tank. The water is cooled by the cooling pipe inside the water tank, so that the water temperature is cooled and the water dissipation is continued to prevent the heat dissipation effect from being reduced. After long-term use, the internal water flow needs to be replaced. The water outlet cover is opened to allow the water to flow out. After the internal water has flowed out, the water outlet cover is closed, and the water inlet cover is opened to pour water in to ensure the cleanliness of the internal water flow and clean the pipeline at the same time.

After long-term use, the internal water flow needs to be replaced, and the water outlet cover 1012 is opened to allow the water to flow out. After the internal water has flowed out, the water outlet cover 1012 is closed, and the water inlet cover 1011 is opened to pour water in.
